+ Changes between 0.9.8b and 0.9.9 [xx XXX xxxx]
+
+ *) In addition to the numerical (unsigned long) thread ID, provide
+ for a pointer (void *) thread ID. This helps accomodate systems
+ that do not provide an unsigned long thread ID. OpenSSL assumes
+ it is in the same thread iff both the numerical and the pointer
+ thread ID agree; so applications are just required to define one
+ of them appropriately (e.g., by using a pointer to a per-thread
+ memory object malloc()ed by the application for the pointer-type
+ thread ID). Exactly analoguous to the existing functions
+
+ void CRYPTO_set_id_callback(unsigned long (*func)(void));
+ unsigned long (*CRYPTO_get_id_callback(void))(void);
+ unsigned long CRYPTO_thread_id(void);
+
+ we now have additional functions
+
+ void CRYPTO_set_idptr_callback(void *(*func)(void));
+ void *(*CRYPTO_get_idptr_callback(void))(void);
+ void *CRYPTO_thread_idptr(void);
+
+ also in <openssl/crypto.h>. The default value for
+ CRYPTO_thread_idptr() if the application has not provided its own
+ callback is &errno.
+ [Bodo Moeller]
+
+ *) Change the array representation of binary polynomials: the list
+ of degrees of non-zero coefficients is now terminated with -1.
+ Previously it was terminated with 0, which was also part of the
+ value; thus, the array representation was not applicable to
+ polynomials where t^0 has coefficient zero. This change makes
+ the array representation useful in a more general context.
+ [Douglas Stebila]
+
+ *) Various modifications and fixes to SSL/TLS cipher string
+ handling. For ECC, the code now distinguishes between fixed ECDH
+ with RSA certificates on the one hand and with ECDSA certificates
+ on the other hand, since these are separate ciphersuites. The
+ unused code for Fortezza ciphersuites has been removed.
+
+ For consistency with EDH, ephemeral ECDH is now called "EECDH"
+ (not "ECDHE"). For consistency with the code for DH
+ certificates, use of ECDH certificates is now considered ECDH
+ authentication, not RSA or ECDSA authentication (the latter is
+ merely the CA's signing algorithm and not actively used in the
+ protocol).
+
+ The temporary ciphersuite alias "ECCdraft" is no longer
+ available, and ECC ciphersuites are no longer excluded from "ALL"
+ and "DEFAULT". The following aliases now exist for RFC 4492
+ ciphersuites, most of these by analogy with the DH case:
+
+ kECDHr - ECDH cert, signed with RSA
+ kECDHe - ECDH cert, signed with ECDSA
+ kECDH - ECDH cert (signed with either RSA or ECDSA)
+ kEECDH - ephemeral ECDH
+ ECDH - ECDH cert or ephemeral ECDH
+
+ aECDH - ECDH cert
+ aECDSA - ECDSA cert
+ ECDSA - ECDSA cert
+
+ AECDH - anonymous ECDH
+ EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")
+
+ [Bodo Moeller]
+
+ *) Add additional S/MIME capabilities for AES and GOST ciphers if supported.
+ Use correct micalg parameters depending on digest(s) in signed message.
+ [Steve Henson]
+
+ *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process
+ an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code.
+ [Steve Henson]
+
+ *) Initial engine support for EVP_PKEY_METHOD. New functions to permit
+ an engine to register a method. Add ENGINE lookups for methods and
+ functional reference processing.
+ [Steve Henson]
+
+ *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of
+ EVP_{Sign,Verify}* which allow an application to customise the signature
+ process.
+ [Steve Henson]
+
+ *) New -resign option to smime utility. This adds one or more signers
+ to an existing PKCS#7 signedData structure. Also -md option to use an
+ alternative message digest algorithm for signing.
+ [Steve Henson]
+
+ *) Tidy up PKCS#7 routines and add new functions to make it easier to
+ create PKCS7 structures containing multiple signers. Update smime
+ application to support multiple signers.
+ [Steve Henson]
+
+ *) New -macalg option to pkcs12 utility to allow setting of an alternative
+ digest MAC.
+ [Steve Henson]
+
+ *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC.
+ Reorganize PBE internals to lookup from a static table using NIDs,
+ add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl:
+ EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative
+ PRF which will be automatically used with PBES2.
+ [Steve Henson]
+
+ *) Replace the algorithm specific calls to generate keys in "req" with the
+ new API.
+ [Steve Henson]
+
+ *) Update PKCS#7 enveloped data routines to use new API. This is now
+ supported by any public key method supporting the encrypt operation. A
+ ctrl is added to allow the public key algorithm to examine or modify
+ the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
+ a no op.
+ [Steve Henson]
+
+ *) Add a ctrl to asn1 method to allow a public key algorithm to express
+ a default digest type to use. In most cases this will be SHA1 but some
+ algorithms (such as GOST) need to specify an alternative digest. The
+ return value indicates how strong the prefernce is 1 means optional and
+ 2 is mandatory (that is it is the only supported type). Modify
+ ASN1_item_sign() to accept a NULL digest argument to indicate it should
+ use the default md. Update openssl utilities to use the default digest
+ type for signing if it is not explicitly indicated.
+ [Steve Henson]
+
+ *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New
+ EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
+ signing method from the key type. This effectively removes the link
+ between digests and public key types.
+ [Steve Henson]
+
+ *) Add an OID cross reference table and utility functions. Its purpose is to
+ translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
+ rsaEncryption. This will allow some of the algorithm specific hackery
+ needed to use the correct OID to be removed.
+ [Steve Henson]
+
+ *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO
+ structures for PKCS7_sign(). They are now set up by the relevant public
+ key ASN1 method.
+ [Steve Henson]
+
+ *) Add provisional EC pkey method with support for ECDSA and ECDH.
+ [Steve Henson]
+
+ *) Add support for key derivation (agreement) in the API, DH method and
+ pkeyutl.
+ [Steve Henson]
+
+ *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support
+ public and private key formats. As a side effect these add additional
+ command line functionality not previously available: DSA signatures can be
+ generated and verified using pkeyutl and DH key support and generation in
+ pkey, genpkey.
+ [Steve Henson]
+
+ *) BeOS support.
+ [Oliver Tappe <zooey@hirschkaefer.de>]
+
+ *) New make target "install_html_docs" installs HTML renditions of the
+ manual pages.
+ [Oliver Tappe <zooey@hirschkaefer.de>]
+
+ *) New utility "genpkey" this is analagous to "genrsa" etc except it can
+ generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
+ support key and parameter generation and add initial key generation
+ functionality for RSA.
+ [Steve Henson]
+
+ *) Add functions for main EVP_PKEY_method operations. The undocumented
+ functions EVP_PKEY_{encrypt,decrypt} have been renamed to
+ EVP_PKEY_{encrypt,decrypt}_old.
+ [Steve Henson]
+
+ *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
+ key API, doesn't do much yet.
+ [Steve Henson]
+
+ *) New function EVP_PKEY_asn1_get0_info() to retrieve information about
+ public key algorithms. New option to openssl utility:
+ "list-public-key-algorithms" to print out info.
+ [Steve Henson]
+
+ *) Implement the Supported Elliptic Curves Extension for
+ ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
+ [Douglas Stebila]
+
+ *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
+ EVP_CIPHER structures to avoid later problems in EVP_cleanup().
+ [Steve Henson]
+
+ *) New utilities pkey and pkeyparam. These are similar to algorithm specific
+ utilities such as rsa, dsa, dsaparam etc except they process any key
+ type.
+ [Steve Henson]
+
+ *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New
+ functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
+ EVP_PKEY_print_param() to print public key data from an EVP_PKEY
+ structure.
+ [Steve Henson]
+
+ *) Initial support for pluggable public key ASN1.
+ De-spaghettify the public key ASN1 handling. Move public and private
+ key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
+ algorithm specific handling to a single module within the relevant
+ algorithm directory. Add functions to allow (near) opaque processing
+ of public and private key structures.
+ [Steve Henson]
+
+ *) Implement the Supported Point Formats Extension for
+ ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
+ [Douglas Stebila]
+
+ *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
+ for the psk identity [hint] and the psk callback functions to the
+ SSL_SESSION, SSL and SSL_CTX structure.
+
+ New ciphersuites:
+ PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
+ PSK-AES256-CBC-SHA
+
+ New functions:
+ SSL_CTX_use_psk_identity_hint
+ SSL_get_psk_identity_hint
+ SSL_get_psk_identity
+ SSL_use_psk_identity_hint
+
+ [Mika Kousa and Pasi Eronen of Nokia Corporation]
+
+ *) Add RFC 3161 compliant time stamp request creation, response generation
+ and response verification functionality.
+ [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project]
+
+ *) Add initial support for TLS extensions, specifically for the server_name
+ extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now
+ have new members for a host name. The SSL data structure has an
+ additional member SSL_CTX *initial_ctx so that new sessions can be
+ stored in that context to allow for session resumption, even after the
+ SSL has been switched to a new SSL_CTX in reaction to a client's
+ server_name extension.
+
+ New functions (subject to change):
+
+ SSL_get_servername()
+ SSL_get_servername_type()
+ SSL_set_SSL_CTX()
+
+ New CTRL codes and macros (subject to change):
+
+ SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
+ - SSL_CTX_set_tlsext_servername_callback()
+ SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
+ - SSL_CTX_set_tlsext_servername_arg()
+ SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_hostname()
+
+ openssl s_client has a new '-servername ...' option.
+
+ openssl s_server has new options '-servername_host ...', '-cert2 ...',
+ '-key2 ...', '-servername_fatal' (subject to change). This allows
+ testing the HostName extension for a specific single host name ('-cert'
+ and '-key' remain fallbacks for handshakes without HostName
+ negotiation). If the unrecogninzed_name alert has to be sent, this by
+ default is a warning; it becomes fatal with the '-servername_fatal'
+ option.
+
+ [Peter Sylvester, Remy Allais, Christophe Renou]
+
+ *) Whirlpool hash implementation is added.
+ [Andy Polyakov]
+
+ *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
+ bn(64,32). Because of instruction set limitations it doesn't have
+ any negative impact on performance. This was done mostly in order
+ to make it possible to share assembler modules, such as bn_mul_mont
+ implementations, between 32- and 64-bit builds without hassle.
+ [Andy Polyakov]
+
+ *) Move code previously exiled into file crypto/ec/ec2_smpt.c
+ to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
+ macro.
+ [Bodo Moeller]
+
+ *) New candidate for BIGNUM assembler implementation, bn_mul_mont,
+ dedicated Montgomery multiplication procedure, is introduced.
+ BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
+ "64-bit" performance on certain 32-bit targets.
+ [Andy Polyakov]
+
+ *) New option SSL_OP_NO_COMP to disable use of compression selectively
+ in SSL structures. New SSL ctrl to set maximum send fragment size.
+ Save memory by seeting the I/O buffer sizes dynamically instead of
+ using the maximum available value.
+ [Steve Henson]
+
+ *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
+ in addition to the text details.
+ [Bodo Moeller]
+
+ *) Very, very preliminary EXPERIMENTAL support for printing of general
+ ASN1 structures. This currently produces rather ugly output and doesn't
+ handle several customised structures at all.
+ [Steve Henson]
+
+ *) Integrated support for PVK file format and some related formats such
+ as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
+ these in the 'rsa' and 'dsa' utilities.
+ [Steve Henson]
+
+ *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
+ [Steve Henson]
+
+ *) Remove the ancient ASN1_METHOD code. This was only ever used in one
+ place for the (very old) "NETSCAPE" format certificates which are now
+ handled using new ASN1 code equivalents.
+ [Steve Henson]
+
+ *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
+ pointer and make the SSL_METHOD parameter in SSL_CTX_new,
+ SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
